LTR systems that I believe are dead

While there are some LTR systems that seem to have less traffic as the operators move them to digital, there are also some LTR systems listed here that do not appear to be active at all.

Posting here to see if others have gotten different results, or if there's interest in removing dead systems from the wiki.

Beltronics: https://scan-ne.net/wiki/index.php?titl ... ations_LTR

I plugged the Goffstown and Pack Monadnock frequencies in and ran LCN Finder on each for several hours recently. Nothing on the Pack Monadnock system. The Uncanoonuc system got two hits -- but both frequencies and discovered LCNs matched the Dispatch Boston system that has some of the same frequencies licensed. I haven't tried the Hollis one yet, but suspect it's probably the same deal. (I have surprisingly bad coverage to Hollis from here.)


County Comms Boston LTR: https://scan-ne.net/wiki/index.php?titl ... ations_LTR

The Georgetown system is active, but the Boston system has no apparent LTR activity on either frequency.

I don't know about the York or Sargents Purchase LTR systems; they're way out of range.


It's hard to prove the absence of a system, but I'd expect at least occasional home-channel data bursts, even if they're not doing periodic CWIDs on the -253 talkgroups.

Yup, hard to prove when it might be a mom n pop enterprise renting it, or such as now [Delta Airlines]
where not much is flying and we have One TG, One Control and One Voice, that has been used 3-5 times in 48 hrs

Hopefully some insiders might chime in, or even PM/Email with more info

Out of the 4 LTR 900MHz systems on the Cape, the only one still used is the Mashpee system. Even at that , most of those users have jumped to ICE DMR systems. The only users left on Mashpee are Joint Base Cape Cod related...very minimal usually Range Control and some vehicle traffic near runways.

Both links are to the same system? Did you mean another system for Beltronics?

D'oh! Yes, meant to link to https://scan-ne.net/wiki/index.php?title=Beltronics_LTR for Beltronics. Will go back and edit my post.

Edit: Nevermind, I can't edit it now.
